DISK

WHEEL.

Application filed Decemberilf), 1925. Serial No. 76,530;

To all whom 'it may concern.'

Be it known that I. THOMAS C.' YoHo, av citizen of the United States of America, residing at Cumberland, in the county of Guernseyr and State of Oliio,`have invented certain ynew and useful Improvementsin Disk lVlieels, of which the following is a specification.

rIliis invention relates to an improvement Ain disk Wheels, involving relatively spaced i inner and outer disk sections, so formed and interconnected as to provide Va rigid construction Whcn in use.

The wheel proper is designed to provide for the convenient removal of the outer disk section When desired to remove 'the-demountable rim,` this outer section being held in place through the use of a single nut, and associated ivith the inner section so that the .20 load stresses ordinarily7 borne by the outer section are transferred in large part to the inner section. I

An object of the invention is theutilization of the main nut, whereby the hub of the Wheel is held on the axle, as a means for overlying and securing the retaining disk in bearing and interlocked connection with the outer disk section; tlie lremoval of this nut freeing` the retainer and permitting 1t and the oiiter 'disk section of the Wheel to be readily removed when desiring to move or apply the usual deinountable tire rim.

The invention is illustrated in the aecompanying drawings` in ivhicli: U

Fig. 1 is a broken vertical sectional vvieu1 *illustrating the construction of the improved Wheel.

Fig. 2 is a broken elevation of the im# proved Wheel viewed from the outer side..

Fig. 3 is an end view oi the hub showing the flange formed with the oval openings for receiving the bolts Jfor the inner edge of the inner disk section. l

Fig. i is a perspective viev of one of the bolts used to secure the brake drum, hub flange, and inner disk section of the Wheel in. relative positions.

The improved Wheel is made up ot an inner disk section 1 ,.and an outer disk section 2, combined with a hub section 3. The inner disk section 1 is formed at its outer-edge to provide a demountable rim receiving lip 4, and inwardly of the lip the section is extended laterally.y in return bend form, to provide what will be termed the Wheel telly 5l This'section 1 is centrally formed with an 4opening 6 of a diameter slightly exceeding that of the inner end of the hub 3, and beyond the edge of this opening is laterally offset at 7 to form an annular shoulder to snugly engage and bear upon the outer edge of an outturned flange 8 at the inner end of the hub. Oiitivardly beyond the shoulder 7, the inner disk section l is extended laterally in return bend form to 'provide a brace 65 column 9, of the full .Width of the Wheel at this point.

The outer disk section 2 which consti.- tutes the removable 4section of the wheel is formed at its outer edge to provide a lip 10, similar to and cooperating with the lip 4, to engage the tire rim, being at the inner margin o'l this` lip inwardly extended to pro-l vide a `ledge 1.1-- to directly underlie the tire rim. Immediately inwardly of the ledge, the disk 2 is recessed at` 12 to accurately receive the free edge of the Wheel felly 5, this felly being formed at an appropriate point. with a pin 13 to pass through an opening in the recess portion of the section 2 to prevent relative rotary movement of the sections.

The central portion of the disksection 2 is formed with an opening 14 to permit the passage therethrough of theK outer end ot'A the hub 3,and beyond the edge of this opening, said section 2 is fornieclwith an annular channel 15 to receive the free end of the brace column 9 of the section 1, the inner portion of this channel 15 forming an abrupt shoulder 16. A retaining disk 17 90 of appropriate thickness is designed to fit over the free end of the hub 3 and snugly Within the shoulder 1G, bearing against that portion of the disk 2 inwardly ot the shoulder. A pin 18 projects from the underlying portion of the disk section 2 and seats in an appropriate opening 1,9 in the inner face of the retainer 17 ,thus securing the inner por- Y tion of the disk 2 against independent rotative movement relative to the retainer` The hub 3 is, for rear wheel. construction,l keyed in the usual manner to the axle 20, the free end of the axle projecting beyond the liub to receive a nut 21, fixed by a Cotter pini' 22. A cap nut 23 forming a grease reservior is placed over the nut 21 and has a threaded skirt to engage a reduced portion 24 of the hub 3. A retaining nut 25 of Sutlifient size and ornamentation to serve as a hub cap is formed with a wrench engaging portion 26 110 :'25 lindricalfterminal 32, the bolt includes an and a cylindrical ange. 27, which extends through the retainer .17 and has threaded connection' at 28 with the hub 3. The retaining nut is adapted to,interlock lrwith the retainer l?, the latter being formed with an annular series of openings 29'in its outer face and the retaining nut being provided,

with a spring pressed pin 30, adapted to Aengage any one of the openings 29 to secure the retaining nut against movement. The spring pressed pin 30 is here shovsn as a spring leaf connected at one end to the retaining nut 25 and carrying the pin 30 at the opposite end,

A though equivalent constructions are contem.

plated.

The rear wheel requires the use of a brake` drum shown at 3l, and this drum is securedto the inner portion of the improved disk Wheelv by a peculiar type of bolt, shown more particularly in Fig. 4. This bolt ycomprises a cylindrical terminal 32 adapted to be more or less freely engaged by an opening 33 1n the innerv disk section l adjacent the inner edge thereof. Immediately beyond the cyoval section 34 adapted to seat in acorrespondingly sized and shaped opening 35 in the flange 8 of the hub 3. Beyond the oval section, the nut includes a reduced threaded terminal: 36 ladapted to bepassed through the Wall of the brake 'drum and said brake drum secured thereon by nuts 37.. lllhe proj ject-ion of the cylindrical terminal 32 beyond the oval portion 34 forms a shoulder which d bearsagainst theinner face of the hub place, though obviously any appropriate' number may be used.

It Will be lapparent thatl with the disk section 2 removed; the demuntable rim 38 carrying the ltire 39, may be readily applied,

following which the disk section 2 is properly positioned and the Wheel is 'ready for use. It is to be noted that the felly 5 inclines toward the outer face of the Wheel, thus enabling the felly to carry a greater .portion of the load on the rim.

y In order to avoid difficulty in iniiating a tire applied -to the Wheel described, I contemplate using with the usual valve stem'40 a conventional clamp 41 Which secures in "communicationwith such valve stein, a lateral tube 42 which extends to'and terminates adjacent an opening 43 formed in the disk i,assnis section 2.` The tube 42 is provided With a cap 44 readily accessible through the opening 4 3, and the latter is preferably provided with a 'removable cap 45, through which, as

will be' apparent, the tire may be readily inl facility ofthe usual' sinI ilated with all the gle disk or spoke Wheel. lf desired, andas preferred, the outer disk '2 may be strengthened'by a .radial lib for mation, as indicated. Furthermore, it is desirable that tlfi. felloe engaging edge ofthe outer disk have the maximum ripping effect to prevent'separation at this point. Lrlo this end, the dish of the disk section 2 is such that it`will engage the felloe of the Wheel heforevit engages the end of the Lbrace column 9, so that-as'the vdisk is forced to posi tion by the nut, the pressure on the free edge of the felloewill increase, thereby tending to prevent separation at thispoint in the use of the Wheel.
